Given:
The coordinate of point R in quadrilateral RUST are (2,4).
R is dilated by a scale factor of 3, centered at the origin, followed by the translation
.
To find:
The coordinates of R' after dilation and translation.
Solution:
If a figure is dilated by a scale factor of 3, centered at the origin, then

We value R(2,4).


The rule of translation is:

Using this rule, we get


Therefore, the coordinates of point R' are (10,12) and the correct option is B.
